Memory and Learning of Objects and Scenes (MAOS)
Head : Emmanuel BARBEAU
The primate’s visual system shows a surprising efficiency. In a fraction of a second, it is possible to detect, categorize, recognize and identify objects in the complex surrounding world. The PROS team focuses on the recognition and the neural representation of objects (common, famous and unique) and object categories. One of its specificity is the use of biologically pertinent stimuli, more specifically photographs of natural scenes.
By combining experimental projects in healthy humans and patients (psychophysic, EEG, fMRI, intracranial recordings) with theoretical approaches and models, the aims of the team include : elucidating the key mechanisms underlying the amazing efficiency of the biological visual systems, analysing how learning and expertise can shape visual representations and the neural substrates ensuring their memorization, describing the effects of healthy and pathological aging.
Computational neuroscience studies have had a major impact. Specifically, via the development of a software for object recognition commercialized through SpikeNet Technology (a spin-off company created in 1999 by 3 of Cerco’s researchers).
